Question

我的数据库中有一个用户，我想编辑他们的信息。我正在尝试添加他们的性别和身高。问题是，更新用户后，我无法再次登录。该错误一直持续存在，并且总是在更新用户后发生。

这是我的 HTML 代码：

<form th:action="@{/editprofile/save}" th:object="${user}" method="post">

还有我的 Controller 代码：

@PostMapping("/editprofile/save")
public String save(@Valid User user, BindingResult result, RedirectAttributes redirect, Principal principal) {
    if(result.hasErrors()) {
        return "views/success";
    }
    System.out.println(user.getEmail());
    System.out.println(user.getPassword());
    System.out.println(user.getRepassword());

    userService.save(user);

    redirect.addFlashAttribute("success", "Saved employee successfully!");
    return "redirect:/editprofile";
}

是的，这都是表格：

Rails.application.routes.url_helpers.generate_csv_admin_event_path(resource, format: :csv)

这是我的控制器保存：

<form th:action="@{/editprofile/save}" th:object="${user}" method="post">

        <div class="form-group row">

用户服务：

 @GetMapping("/editprofile")
public String editeProfile( Model model, Principal principal) {

    String email = principal.getName();
    User user = userService.findOne(email);

    model.addAttribute("user", user);

    return "views/editprofile";
}


@GetMapping("/editprofile/{email}")
public String editProfile( @PathVariable String email, Model model,Principal principal) {

    model.addAttribute("user", userService.findOne(email));
    return "views/editprofile";
}



@PostMapping("/editprofile/save")
public String save(@Valid User user, BindingResult result, RedirectAttributes redirect) {
    if(result.hasErrors()) {
        return "views/success";
    }
    System.out.println(user.getEmail());
    System.out.println(user.getPassword());
    System.out.println(user.getRepassword());

    userService.save(user);

    redirect.addFlashAttribute("success", "Saved employee successfully!");
    return "redirect:/editprofile";
}

感谢您遵循我指导的方法 https://stackoverflow.com/a/53371025/10232467

在给定的源代码中未定义身份验证和授权过程。我们应该使用Spring Security来完成这项工作。请导入spring安全依赖项，并按如下所示创建Security配置类

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
    http
            .authorizeRequests()
            .antMatchers("/").permitAll()
            .anyRequest().authenticated()
            .and()
            .formLogin()
          //  .loginPage("/login") in case if custom login page is required
            .permitAll()
            .and()
            .logout()
            .permitAll()
    // add ant matchers and require secure in case if certain url has to be on https
    ;
}

@Bean
public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
}

// for in memory authentication
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.inMemoryAuthentication()
            .passwordEncoder(passwordEncoder())
            .withUser("user")
            .password(passwordEncoder().encode("password"))
            .roles("USER");
}
}

您可以通过以下代码随时在控制器中登录用户详细信息

  Authentication auth = SecurityContextHolder.getContext().getAuthentication();
  String name = auth.getName(); //get logged in username

为什么更新数据库中的行后出现登录问题？
